Enclosure Types
Before Deciding on a particular type of enclosure to use, you must first determine the amount of space you have available. This is a very important step to ensure you have the appropriate volume needed to provide proper performance of the subwoofer. For example, if you wish to build an enclosure for a 15″ and you only have one cubic foot space available, it would be better to use a 10″ because the volume is not large enough to allow the 15″ to perform properly. The small enclosure would restrict the performance of the 15″ not allowing it properly reproduce low frequencies.Sealed Enclosure:

Advantage: Bandpass can be designed to play loud or low depending on your needs, by design produce a limited band with, the woofer cone does not move as much as other designs reducing the chance of added distortion.

Disadvantage: Bandpass boxes have a tendency to sound boomy not tight, typically these enclosures don’t sound as good reproducing music requiring great detail such as jazz or classical music.

Enclosure Material

It is recommended to build your enclosure from 3/4″ thick MDF (medium density fiberboard). Make sure the enclosure is sealed air tight.
